'those going in while others out?' is the definition.
I can't tell whether this defines the answer.

'hit riding waves' is the wordplay.
'hit' becomes 'strike' (synonyms).
'riding waves' becomes 'breakers' (breaker is a kind of wave. I am not sure about the 'riding' bit.).
'strike'+'breakers'='STRIKEBREAKERS'
